Hmm, let's say they pay YC their liquidation preference, pay Milner's note, and give the team a small signing bonus and new salaries for the new mission.

>I am not sure why this is being touted as a "hidden" gem, it was on the feature list and expounded as much as many of the other features in iOS6.

Because many people don't yet know about it? As if people read the "feature lists"...

>It is inexcusable that it wasn't previously possible to upload photos to sites (one of what is now the most common use cases for the internet) without involving a native app. The iOS ecosystem struggles to find a middle ground between native and a competitive/competent browser. This feature was no doubt strongly argued by Apple's PMs for many years, but finally they won out over some other dept's PM team.

I seriously doubt this conspiracy theory. How about, they just got around to it? It also took Android a version or two to add the same feature -- and Mobile Safari has been more feature complete AND faster than the built-in Android "Browser" for years, so it's not like they tried to stifle mobile apps.

(As a matter of fact, when Jobs touted mobile apps as the way to build applications for the iPhone (pre SDK), people were frothing at the mouth, demanding a native SDK).

I disagree. PayPal is NOT regulated as a bank in the United States. Here is an article from 2002 when they received the official word that they would not be regulated as a bank:

http://www.ecommercebytes.com/cab/abn/y02/m03/i13/s03

They _are_ regulated as a money transferral service. I work for a bank and I can assure you that the level of scrutiny by banking regulators is _far_ greater. As a single for-instance, the auditors have asked to see documentation of our software development methodology (presumably to ensure there were procedures in place to ensure applications were built securely and without an opportunity for an attacker to check in some kind of back-door).

The best code challenge I was given was to build an infinite scroll implementation. The company gave me an API endpoint that spat out JSON, and my assignment was to create a page that would show the items and render more items from the endpoint when you scroll down to the bottom of the page. I was given no time limit. They just said "send us the code in email when you're done". I was allowed to use anything I wanted. I finished in about 6 hours. Most of the time was spent going through the bajillion endless scroll jquery plugins (99% of all jquery plugins are total crap). It was fun for me, and I was allowed enough time to polish up the code to get it looking like code I normally write. Now if I ever want to implement infinite scroll in any of my personal projects, I know how to do it.

The worst code challenge I was given was by a company that basically gave me a huge dump of data (a 60 line string in a very peculiar format) and told me to write a function that took the data, processed it, then outputted that data in another peculiar format. I was given one hour to complete this assignment. It was tedious and in no way fun, so I just didn't do it. I probably could have gotten it, but I don't like doing things like that. If the interview contains high-stress speed coding, then I can only assume the job contains the same. No thanks.

Good developers like to take their time, so don't timebox (at least not in units of hours, a one week deadline is fine). Also, good developers don't like doing tedious things. Give them something meaningful to do, not just busywork.

so from what I understand, the air bends around a surface the way water sticks to the side of a teapot. The nozzle design has a "step", a little cutout at the top of the curve closest to where the air is exiting from. This little step causes a small vortex, or eddy, like in a river. The vortex causes an area of lower pressure which bends the stream of air. You can clearly see the exhaust nozzles on "fig-1" of the declassified documents:

Nope, both are fusion reactions. You fuse two particles together below 56 on the periodic table and achieve energy. After 56 and up, you have to use fission, where you split atoms apart, to achieve energy.

Tritium is part of the fuel for this type of fusion reactor. Since tritium basically doesn't exist in nature (due to its twelve-year half-life), the reactor will produce it by absorbing as many neutrons as possible in a blanket of lithium.

Short answer: Yes.

Long answer: I'm not quite sure what you mean by "working out equations". Category theory is useful. Categories were introduced by Eilenberg and MacLane to formalize certain structures were studying in the context of algebraic topology (homology, cohomology and homotopy are all functors from topological to algebraic categories, and there are lots of examples of natural transformations on these functors). Algebraic topology is a foundation for quantum/low-dimensional topology, so categories naturally arise in using the tools from algebraic topology.

In quantum topology, many of the natural invariants one studies are in some sense TQFTs: Topological Quantum Field Theories. The modern formulation of TQFTs is due to Atiyah. In this formulation, a TQFT is a functor from a certain kind of topological category called a cobordism category (in analogy with physics, one can think of the objects as spacetimes and the morphisms as spacetime evolution) to certain algebraic categories (which one can think of as quantum state spaces and evolution operators). These TQFTs are often not just functors, but n-functors: the categories in question are not just regular categories, but higher categories or infinity categories.

I didn't know about it and I watched the iOS6 presentation, skimmed through the iPhone 5, iOS 6 apple.com pages, regularly read 2-3 Apple websites + HN, and am a web developer.
The web is constantly being developed and changing, a system does not evolve as quickly and is not in a constant state of development.

That would be my guess anyways.

You can ask it to explain what it did, just like you'd ask for the last error. Then in your app enforce whatever rules related to indexes you wish.
The first fission plants will involve neutrons, but aneutronic fission would be the next step after that. It would require getting the fire hotter/denser.

"Never use early exits" is exceedingly bad advice, in my experience. What has led up to your claim that early exits are bad? As I've gained experience, I find myself writing code like this more and more:

if (UnexpectedOrUnhandledCondition(x)) {
...
return false;
}

if (OtherError(y)) {
return false;
}

and so on. Serial code like that is trivially easy to understand when reading; more importantly, six months later, it's far more explicit and easier to comprehend than the comparable single-exit version.

The alternative to early exits is nesting, and nesting is the readability killer. My experience has apparently been just the opposite of yours: that avoiding early exits is a sign of a junior programmer, and returning early whenever possible is a sign of an experienced programmer who knows that understands code maintenance.

> The idea that there isn't a file system is nothing more than a suspension of disbelief, of course there's a file-system, it's just that there are folder handlers that know how to render the contents

This is both the strength and weakness of iOS and for the most part, it's a benefit to the vast majority of it's main users (ie, not you or me). Have you looked at a non-techie's folder recently? It's a complete nightmare, and without a really good indexer and search system (OSX is ok, Windows sucks, not sure how Linux fares these days) it's nigh impossible for those users to find their saved documents - was that Tomorrow's Picnic Details.xls or did I convert it from the downloaded .csv? Maybe I only preserved it as an attachment that lives in a mail item in my inbox?

Ideas are one thing, execution is another. The fact that file uploads didn't exist forced app developers to be creative in how they managed local storage on iOS - glad the feature is there now, but I can see why Apple didn't include it originally.

I think it is very very important to not ignore traction boosting activities early on. It is very important to build a brand, get users engaged, and have people ready to try out your product when it launches. I think one thing that the article doesn't mention though is that if you are doing this before you are delivering value to customers with your product, you need to make sure your messaging is not just trumpeting your horn. The communication/engagement strategies should be building real value for your potential customers. People just tend to pay more attention to people who are constantly providing them things of value. Lots of people forget or don't realize that the value you provide doesn't only come from your product.

Don't over-think this, kids.
Nearly infinite odds are that it was canceled because it didn't work.

From TFA:
One declassified memo, which seems to be the conclusion of initial research and prototyping, says that Project 1794 is a flying saucer capable of "between Mach 3 and Mach 4," (2,300-3,000 mph) a service ceiling of over 100,000 feet (30,500m), and a range of around 1,000 nautical miles (1,150mi, 1850km). [...] According to the cutaway diagrams, the entire thing would even be capable of vertical takeoff and landing (VTOL).

VTOL, Mach 3++, 100,000ft - the only thing it was missing for it to be the perfect military aircraft is a Romulan cloaking device.

If the "flying saucer" could meet those specifications, it would still be classified. Q.E.D. it didn't work.
I agree, it does seem like they are steering their users toward posting more photos.

I guess I am skeptical that they can pull that off without an accompanying bookmarklet, web upload flow, or mobile app.
Actually large format data displays are great for calling out unexpected transitions. I had a chance to look at the control panel of a nuclear reactor for an aircraft carrier once, and what I learned was that the panel had annunciator lights that would blink on an 'unexpected' change. So for example steam pressure would by static in one of two states (cold shutdown, operation) and smoothly changing when state changing, so the light would start blinking if either the steam pressure changed when the reactor wasn't changing state, or if it stopped changing in the correct way when the reactor was changing state.

Looking across a sea of lights, if you saw one that was blinking you would go over to it, read off the legend (that would tell you the conditions under which that light would blink) and then take action. Once action was in process you pushed the button to 'acknowledge' the anomaly. (which also set new parameters for when it would start blinking again)

All in all a very cool system. I've been sorely tempted to hack something similar for our search and crawling clusters. Sadly I don't think its practical to have a mockup of the Enterprise-D warp core which pulses in response to query rate, although that would be very very cool :-).

Some do, most don't. Saturn V could (and did several times) survive failure of a first-stage motor. STS (Shuttle) theoretically could survive an engine loss under some conditions. The Soviet N1 could well have survived a motor loss (it had 30 of them after all), had it flown and had they been able to control all those engines.

Historically, most rocket designs push the performance envelope so hard they have little or no margin. Much of this attitude is historical, government rockets mostly being descended from ICBMs. The other part is that the rocket equation severely penalizes extra weight, and the window between "robust" and "too heavy to fly" isn't all that large.

I'm now 3-months in to my own gap year and I'm loving it. I'm working in the bay area, not teaching in an impoverished country, but it's been a huge kick-in-the-ass to grow up. Dealing with rent, eating healthily, managing money — it's been both more difficult and more interesting than I expected. I've gained a lot of respect for my parents with regards to simply keeping a family going. Not to mention the incredible things I'm learning from working and socializing with people much older than me. If anyone else out there is considering a gap year I say: go for it.
Then again, the probability of failure on the single-engine component is only a ninth the probability of failure on the nine-engine component (assuming there are no other factors, which of course isn't a safe assumption, but I don't know how to adjust).
This all looks very cosy with all these companies supporting it, but I wonder how this site will deal with the more political aspects of web technologies. For example, it's still totally ridiculous that there is not one audio or video format that plays everywhere. You have to dual-encode to two formats. So if you make a game with sound effects, you have to find both a Vorbis and AAC encoder, and if you want to host a video you'll need Theora and H.264 or whatever the deal is there, and so on. So what will WebPlatform.org recommend, given how obvious it is that one format would be far simpler and make for a better platform? Will it side one way or another? Will this upset their "stewards"?
This sounds vaguely familiar...

> SpaceX update: The engine did not explode

No, it just became a "Falcon 8" while enroute.

All joking aside, as a former NASA Space Shuttle engineer I'm very impressed by this private-enterprise venture into heavy-lift launch services. People have often speculated about how much cheaper launch services might be if they were in the private sector -- now we can find out. The preliminary signs are very good.
Clean, yes.

By any measure, cleaner than what else is out there. Already a fission nuclear power plant will produce less leakage of radioactivity into the environment than many coal plants, fusion drops that level several orders of magnitude more.

First off, no fission products, which are typically the most dangerous radioactive waste from fission reactors. Second, the materials used in the reactors don't have the same engineering constraints that fission reactors do and so can be chosen to produce far lower quantities of hazardous radioactive isotopes bred from intense neutron flux bombardment. Also, Tritium is a fuel, and of enormous value so it would be handled very carefully. More so, it would be bred specifically in custom built containment vessels within the reactor.

On top of all that you have the fact that a fusion reactor cannot be made to undergo a meltdown or overload the way a fission reactor can. If something bad happens in a fusion reactor the immediate result is usually that fusion stops, which compares very favorably to the what happens in a fission reactor: fission chain reactions continue, temperatures build as the heat from fission products decaying builds up, etc. And you don't have weapon proliferation concerns.

Overall what you have with nuclear fusion reactors is no chance of a meltdown, very much less hazardous waste generated (by orders of magnitude) and a very clean energy profile.
